mentalities gives best results, as it enables the welding electrodes to follow the link ends as the lattersoften and move into alinement.

In the drawings, Fig. 1, the heated portions of the link ends are represented by dotted lines, and in Fig. 2 I hare indicated the approximate yzone of the Welded joint by a dotted line, although it Willbe under stood that the line of junction Wholly disappears owing to the low or run of the metal during the-forming process.

In order to give the link a finished appearance, I may, if desired, apply a finishing and final shaping pressure to the link in the zoneof the weld and preferably while the link retains some portion of its Welding heat and is, therefore, somewhat soft and easily shaped. -The pressing and shaping instrumentalities are shownconventionally in the drawings in Fig. 3-at 5 and 6. j

What I claim, therefore, and desire to se- .cure by Letters Patent is:

1. The method of welding overlapping beveled ends of metal ivhi'ch consists vin oversetting said beveled ends to extend partially beyond each other, and applying electric ;...belyeled ends of metal 401. :i beyond each other, and applying electricl Welding heat tol said ends with pressure `transversely of the `plane of the beveled heated ends and in 4a direction to press said` heated ends intoalinement. l

`2. The method of Welding overlapping which elonsists in oversetting said beveled ends to'jextend partially .welding heat to said ends with pressure 5, Vtransversely ofY the plane of the beveled heated ends and in a, direction to press saidl .heated ends into alinement, and then apply- .ing finishing shaping pressure to the welded: 'Oint' J 3. The vmethod of. Welding overlappingf beveled ends of metal which consists in'overi setting said beveled ends to extend parl tially beyond each other, and applying elec-y tric Welding heat to said ends with pressure. transversely of the plane of the beveled heated ends and in a direction to vpress said heated ends into alinement, and then applying finishing shaping pressure tothe welded 4.- The method of Welding beveled overlapping ends of metal which consists in oversetting said ends to extend partially beyondr each other, and applying electric Welding lheat to said ends With yielding pressure Vtransversely of the plane of .the bevel of the-heated ends and in a direction to press said heated ends into alineinent,

5. The method of Welding beveled overlapping. `ends of metal which consists in oversetting said ends to extend partially beyond each other and applying simultane- `ously to said endselectric Welding heat and pressure transversely of the plane of the bevel of said heated ends and in a direction to presssaid ends into alinement.

6.. The method of Welding beveled overlapping ends of metal which consists in oversetting said ends to extend partially beyond each other and applying simultaneously to bevel of lsaid heated ends' and in a direction to press .said ends into alinement.` y

7. The method of Welding beveled overlapping ends of metal Which consists in over- `setting said ends to extend partially beyond each other and applying simultaneously to said ends electric welding heat and pressure transversely of the plane of the bevel of said heated ends and 'in a direction to press said ends into alinement, and then applying finishing shaping pressure to the Welded joint.

8. The method of Welding the `beveled overlapping ends of a metal link which consists in oversetting the ends of said link and then applying electric Welding heat to said ends With pressure transversely of the plane of said bevel and in a direction. to press said ends into alinement.

'The method of Welding the beveled overlapping ends of -fa metal link which consists in oversetting the ends of said link and lthen applying electric Welding heat to said ends with pressure transversely of the plane of Said bevel and'in a direction to press said ends into alinement, and then applying finishing shaping pressure to the Welded joint. y y
